jenkins cli，使用groovy脚本签出Subversion [英] jenkins cli with checkout Subversion using groovy script

问题描述

有没有一种方法可以通过在主服务器上执行常规脚本来使用Jenkins-Cli签出任何Subversion项目?我可以说是创建SVN客户端管理器[org.tmatesoft.svn.core.wc.SVNClientManager]的要点，但是真的无法理解如何从URL中签出SVN项目.

Is there a way to check out any Subversion project using Jenkins-Cli by executing a groovy script on the master? I can get to the point of creating SVN client manager[org.tmatesoft.svn.core.wc.SVNClientManager], but can't really understand how to employ that in checking out an SVN project from the URL.
